Kyron Horman Still Missing After Science Fair: Skyline Elementary

From the very start, I thought it was the step-mom. But it's very bizarre that the dad has custody over the real mom, since moms are the primary caregiver and get the custody. It makes you think something is wrong with the real mom. Also this is an FBI case, and FBI cases are not usually for things like this (FBI is usually involved when someone takes him to another country -- maybe a relative took him to protect him from harm). Also there was NO amber alert and people are calling this an Isolated case. It's sad to say, but Kyron has 2 step-parents and a mom who he sees once every 2 weeks and lives with his dad, possibly he's getting abused (sexually or emotional) at home. Maybe the step-mom knew he was being abused, tried to take him to safety. Maybe that's why the step-mom doesn't act so sad, is because she knows he's safe and she knows where he is. I honestly think this is a family situation not a stranger/predator abduction. And I think the reason why they aren't divulging info (the famliy/police) is because it's a family matter and I don't think it's meant for public interest. This whole thing is weird, and I think it's definitely a set up or at least it was planned. Is there anyone in Kyron's family who was abused as a kid (mom, dad, step dad, step mom)? It's weird that that the real mom hasn't even spoken also, let alone the dad. The step mom's attitude is definitely bizarre, but I do think she has to do with his disappearance possibly in a positive way.
